Full hydraulic screw-up, AGC auto-control; rolled rolls sectional cooling to get better plate shape; Fault self-diagnose, alarm and broken strip auto-protection.
The 4-hi reversing mill is the most widely used medium and heavy plate mill in modern times. It combines the advantages of a 2-high reversing mill and a 3-hi Lauter mill. The back-up roll and work roll are completely divided, which not only reduces the rolling force, but also greatly increases the rigidity of the rolling mill. Therefore, it is suitable for rolling medium and thick plates of various sizes, especially those with large rolling width, and plates with strict precision and plate shape requirements.
